Blue-blocking Glasses for Sleep Disorders in Child and Adolescent Psychiatry

Sleep problems and regulation difficulties are frequent in the child and adolescent psychiatry population. Insomnia and delayed sleep-wake phase disorders (DSPWD) are highly prevalent, and risk factors for developing more severe illness courses and chronic disorders. Pharmacological treatments of sleep disorders dominate even for the youngest patients but are unsupported by long-term data on outcome and side effects. The majority of non-pharmacological treatment options are composite and resource demanding. The investigators will examine the effects and feasibility of the isolated intervention of evening/night use of blue-blocking glasses/real darkness as adjunctive treatment for insomnia and delayed sleep phase disorder in inpatient and outpatient settings for children and adolecents.
